Wireless Sensor Network (WSN) performs energy extensive tasks and it is essential to rotate sensor nodes frequently so that Cluster Head selections can be made efficiently. In this paper, we aim to improve the lifetime of sensor network by using LEACH based protocols and efficiently utilizing the limited energy available in these sensor nodes. In sensor network, the amount of data delivered at the...
Here we propose an analytical model of energy usage hierarchical wireless sensor network protocols such as LEACH [1]. LEACH has been used as a foundation for much of the wireless sensor network research, so results addressing the underlying nature of these systems build understanding of a wide range of existing protocols. First, we derive the probability density functions of the distance to the nearest...
Energy Efficient Routing is a crucial issue in Wireless sensor networks (WSNs). This paper proposes a novel algorithm, Parametric Protocol for Energy Efficient Cluster Head Selection (PPEECS) in WSN, which consists of two phases; Region formation phase and Cluster Head (CH) selection phase. In prior phase we divide the network into several regions depending upon node density distribution. The later...
